碳纳米管导电网络结构对无纺布抗静电整理的研究

Effect of carbon nanotube conductive network structure on non-woven fabric antistatic finishing

采用碳纳米管分散液对无纺布进行抗静电处理,使其在无纺布表面形成导电网络,以期达到抗静电的效果。通过调整碳纳米管分散液的质量分数与浸渍方式,探讨了碳纳米管对无纺布进行抗静电整理的规律。结果表明:随着浸渍次数的增加,CNT分散液质量分数越高,受浸渍次数的影响越小;随着CNT分散液质量分数的增加,碳纳米管的直接接触和电子隧道效应均有显著提升;采用浸渍干燥法所制备的抗静电无纺布的工艺参数存在一个配合的阈值。该整理方法简单、易操作,且通过调整浸渍次数或CNT质量分数均可达到较好的抗静电效果。

The antistatic treatment of non-woven fabric is carried out with carbon nanotubes dispersion, which can form a conductive network on the surface of the fabric to achieve antistatic effect. By adjusting the concentration and dipping method of carbon nanotubes dispersion, the principle of carbon nanotubes on non-woven fabric antistatic finishing is explored. The results show that with the increase of impregnation times, CNT dispersion concentration is higher, and its influence is smaller; with the increase of CNT dispersion concentration, the direct contact of carbon nanotubes and electron tunneling effect are significantly increased ; impregnation drying method of preparation of antistatic non-woven process parameters has a fit of the threshold. This method is easy and simple to operate, and good antistatic effect can be achieved by adjusting the impregnation times or CNT concentration.
